Thermal Dissipation Holder

1. A thermal dissipation holder, for a handheld electronic device, comprising: a main structure, having a front surface and a rear surface, wherein the rear surface has a carrier, and the carrier is applied to carry the handheld electronic device; a movable element, movably connected to the main structure along a first direction and having a clamp portion at a side away from the carrier; an elastic element, wherein one end of the elastic element is connected to the main structure, the other end of the elastic element is connected to the movable element, and the elastic element drives the movable element to move along the first direction; and a locker, disposed in the main structure and having a locking portion, wherein a position of the locking portion corresponds to that of the clamp portion, and the locker is selectively engaged with the clamp portion through the locking portion to lock the movable element, wherein the locking portion is movably disposed in the main structure along a second direction, and the second direction is perpendicular to the first direction.

2. The thermal dissipation holder according to claim 1, wherein the clamp portion comprises a locking opening, and the locking portion is coupled to the locking opening to lock the movable element.

3. The thermal dissipation holder according to claim 1, wherein the main structure has two slide grooves extending along the first direction, and the movable element comprises two sliding portions, sliding into the two slide grooves respectively.

4. The thermal dissipation holder according to claim 3, wherein the main structure further comprises a thermoelectric cooling chip disposed between the two slide grooves.

5. The thermal dissipation holder according to claim 1, further comprising a key movably disposed on the front surface along a third direction, wherein the key is coupled to the locker.

6. The thermal dissipation holder according to claim 5, wherein the key comprises an abutment surface for abutting against the locker to drive the locking portion to move away from the clamp portion.

7. The thermal dissipation holder according to claim 1, wherein the locker further comprises two elastic portions, and the two elastic portions are located at two sides of the locking portion to drive the locking portion to move toward the clamp portion.

8. The thermal dissipation holder according to claim 7, wherein the elastic portion is has a wavy structure.

9. The thermal dissipation holder according to claim 1, further comprising a support member pivotally connected to the carrier to switch between a folding position and a supporting position.
